Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing display panels experience signal instability due to varying resistance values in traces connecting signal pins to the drive circuit, leading to different signal strengths and poor display performance.
Innovation Solution
The display panel design includes a substrate with a drive circuit and multiple signal pins connected via traces, where at least two pins are electrically connected, either through a shared trace or different traces, to balance voltage signals and improve signal stability, with the traces potentially arranged on the same or different layers to facilitate manufacturing and signal transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If signal pins are connected to drive circuit via traces with different lengths, then the display panel can accommodate more signal pins, but the resistance values vary causing signal instability
Solution Approach 1:
The patent connects multiple first signal pins (at least two pins) in parallel to create equipotential connections, ensuring that all connected pins have the same electrical potential. This eliminates voltage differences caused by varying trace lengths and resistance values, thereby stabilizing signals across all signal pins while maintaining the ability to accommodate multiple pins.
Solution Approach 2:
The patent merges multiple first signal pins into electrically connected groups, where at least two pins are connected together through conductive structures. This combining approach allows the pins to function as a unified electrical connection point, reducing the impact of individual trace variations and improving overall signal reliability.
2Ease of manufacture
If traces are arranged on different layers, then manufacturing flexibility is improved, but device complexity increases
Solution Approach 1:
The patent utilizes multiple layers (z-dimension) for trace arrangement, allowing traces to be distributed across different layers to connect signal pins. This dimensional approach provides manufacturing flexibility by enabling traces to route around obstacles and connect pins more efficiently, while the layer structure itself manages the complexity through organized vertical stacking.
